      Accés restringit per política de l'editorial
      In this paper, a uniplanar RF-MEMS secondorder bandpass filter with reconfigurable centre frequency is presented. It is based on quarter-wavelength slotline resonators and CPW-slotline multimodal immittance inverters (MIIs), ...
    • Reconfigurable uniplanar bandpass filter based on RF-MEMS switched capacitors 

      Contreras, Adrián; Pradell i Cara, Lluís; Casals Terré, Jasmina; Giacomozzi, Flavio; Iannacci, Jacopo; Ribó, Miquel (2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, an uniplanar RF-MEMS second-order bandpass filter with reconfigurable centre frequency is presented. It is based on half-wavelength slotline resonators, which are loaded using RF-MEMS switches connected ...
    • RF-MEMS switches designed for high-performance uniplanar microwave and mm-wave circuits 

      Pradell i Cara, Lluís; Girbau Sala, David; Ribó Pal, Miquel; Casals Terré, Jasmina; Lázaro Guillén, Antonio; Contreras Lizárraga, Adrián; Llamas Morote, Marco Antonio; Heredia Vega, Julio César; Giacomozzi, Flavio; Margesin, Benno (IntechOpen, 2018-07-18)
      Capítol de llibre
      Accés obert
      Radio frequency microelectromechanical system (RF-MEMS) switches have demonstrated superior electrical performance (lower loss and higher isolation) compared to semiconductor-based devices to implement reconigurable microwave ...
    • RF-MEMS switches for a full control of the propagating modes in uniplanar microwave circuits and their application to reconfigurable multimodal microwave filters 

      Contreras Lizarraga, Adrián Arturo; Casals Terré, Jasmina; Pradell i Cara, Lluís; Ribó i Pal, Miquel; Heredia Vega, Julio César; Giacomozzi, Flavio; Margesin, Benno (2017-03-29)
      Article
      Accés obert
      In this paper, new RF-MEMS switch configurations are proposed to enable control of the propagating (even and odd) modes in multimodal CPW transmission structures. Specifically, a switchable air bridge (a switchable ...
    • RF-MEMS uniplanar 180° phase switch based on a multimodal air-bridged CPW cross 

      Llamas Morote, Marco Antonio; Girbau Sala, David; Ribó, M.; Pradell i Cara, Lluís; Giacomozzi, Flavio; Colpo, S (2011-07)
      Article
      Accés restringit per política de l'editorial
      In this paper, a new compact broadband uniplanar 180 phase switch, based on an air-bridged coplanar-waveguide (CPW) cross loaded with two capacitive-contact microelectromechancial systems (MEMS) switches in opposed (ON/OFF) ...
    • RF-MEMS uniplanar 180º Phase Switch based on switching between two out-of-phase paths 

      Llamas Morote, Marco Antonio; Pradell i Cara, Lluís; Girbau Sala, David; Ribó, Miquel; Lázaro Villa, José Antonio; Giacomozzi, Flavio; Margesin, Benno (2011)
      Article
      Accés restringit per política de l'editorial
      A phase switch based on switching between two twoport passive networks with a phase difference of 180º is reported. Two RF MEMS single-pole-double-throw structures are used to select the phase path. The fabrication is ...
